ItemElectrical tuning of reflectance of graphene metasurface for unpolarized long wavelength infrared lightShrestha, VR ; Gao, Y ; Amani, M ; Bullock, J ; Javey, A ; Crozier, KB (OSA, 2018-01-01)We demonstrate a graphene-metal metasurface for unpolarized long wavelength infrared light with electrically-tunable reflectance. By applying a gate voltage, we shift the wavelength of a resonant reflectance dip centered at ~9.4 micron by~156 nm.

ItemMid-infrared computational spectroscopy with an electrically-tunable graphene metasurfaceShrestha, VR ; Craig, B ; Amani, M ; Bullock, J ; Javey, A ; Crozier, KB (OSA - Optical Society of America, 2019-01-01)We demonstrate graphene-plasmonic metasurfaces whose mid-infrared reflection spectra are electrically-tunable. Using measurements of the power reflected by the metasurfaces at different drive voltages, the source spectrum is computationally reconstructed by the recursive least squares method.
